Link asterisk server to call carrier

Hi there, I have a web platform designed with PHP that stores audio files and call lists from user accounts. Users place "calls" which right now forward the audio and call list to my company so that we can run the calls through a wholesale call center and then manually post the results file back to the platform. We're ready to move out from under our reseller position and actually begin sending the calls ourselves. Basically, we need an experienced professional who can link up an asterisk server like this: [login to view URL] to a call carrier like this: [login to view URL] We need the system to be able to place calls using phone numbers queued in a MySQL database and return dial/call results back to MySQL. We need voicemail detection so that the audio is left when a call isn't answered, bad number recognition to post back with call results, and the future scalability to work polls and transfer calls. The web platform is essentially built, we can post and queue phone numbers in MySQL and plant audio files in a files directory, we really just need the phone numbers to leave the MySQL database, pass through the Asterisk server to the carriers so that the calls are placed, and then post back to MySQL with the call results. Please send me a message if you need any additional information! Thanks!
